Description
Product Description
The Siemens 1FT7084-5AC7X-1XXX is part of the SIMOTICS S-1FT7 family of permanent magnet synchronous servo motors, engineered for high-performance motion control applications that demand exceptional precision, high torque density, and rapid dynamic response. Designed for seamless integration with Siemens SINAMICS S120 servo drive systems, this servo motor family is ideal for CNC machine tools, industrial robotics, packaging machinery, material handling systems, printing equipment, semiconductor manufacturing, and automated production lines.
Operating at a rated speed of 2,000 RPM, the 1FT7084-5AC7X-1XXX series delivers 3.54 kW rated output power, 16.9 Nm rated torque, and 20 Nm stall torque (100 K). The motors provide up to 81 Nm maximum torque and support maximum mechanical speeds of 8,000 RPM, ensuring outstanding acceleration, precise positioning, and reliable continuous-duty performance. The permanent magnet synchronous design offers high efficiency, low rotor inertia, and excellent overload capability.
The 1FT7084-5AC7X-1XXX family is available in multiple MLFB variants featuring different encoder technologies, shaft configurations (plain shaft or keyed shaft), optional holding brakes, connector orientations, and balancing grades. All models include natural cooling, IM B5 flange mounting, DRIVE-CLiQ communication, integrated motor temperature monitoring, rotatable power connectors, and IP65 protection. The exact mechanical and electrical configuration is determined by the complete Siemens MLFB ordering code.
